Waste management complexities

Since starting my career in the environmental sector more than 10 years ago, I’ve been dealing with waste management issues. Frankly, the circular economy wasn’t spoken of yet. And in any case, a lot of the waste generated cannot be recycled. The fact is that we never even quite gone into the first ‘R’ of the three ‘R’s yet.

The thing is, as the country’s population grew and economic activities multiplied, waste growth continued. There was probably a dip in terms of per capita waste generation, but the overall amount of waste we were disposing of grew even if the gross waste generation didn’t quite reach the ‘peak’ we had in 2017.

Our ability to manage this waste is important and it is largely because we’ve been able to get rid of them and maintain the cleanliness of our city, and not burden our businesses with the excessive waste that we have been able to keep up with our economic growth and remained an attractive destination for business, and economic activities. These are, of course, the positive externalities of having a robust waste management programme.

Yet waste is a complicated matter; the fact that waste management produces a positive externality doesn’t necessarily mean that we need to have more of it because that is usually based on the amount of waste that needs to be managed. On the other hand, when you subsidise the management activity, there is a risk that you’re undercharging the people generating the waste, which is the source of the problem in the first place. That brings us beyond the territories of your traditional economic externality analysis.

So, it becomes a political issue. And there’s even a question of willingness to pay, not in the traditional sense that people will not do it anymore. It is about how much you can keep charging the people without losing political support and risking losing votes. This is why public policy surrounding waste is complex, and you can’t leave it to a technocratic government to solve such a problem. You can employ some of the technocratic arguments to help you get some buy-in, but you’d likely need to deploy more tactics than that.

Geopolitics-driven transition

There is increasing acknowledgement of China’s leadership in a huge range of technologies around the energy transition and yet the struggle is that a lot of narratives in the Anglo-saxon world seem to be rather negative about this whenever the conversation on economics of equipment starts talking about using Chinese products.

I’m not sure if trying to re-invent the Chinese leadership in the technologies should be a key priority. Isn’t it the typical ‘western’ idea of trade that every country can develop their comparative advantage and should stick to it? One of the huge comparative advantage that the west has lies in taking seriously very preliminary, immature and ill-formed ideas and persistently exploring, improving, refining them until they are good enough for the market. At that point, the Asian economies with its ability to scale up further and drive costs down takes over those hardware aspects and this allows for prosperity and mutual gains.

The innovations in business model, technology and regulations that are needed probably will proceed the same way. Geopolitics can seem to drive the climate transition at times (such as putting a price on carbon, regulating flow of goods based on carbon content, enforcing carbon disclosures for companies, etc.), but they could also drive things in another way. When America or Europe puts tariffs on China batteries and other technologies, it can set back more advanced technologies that their local ecosystems are trying to build on top of solar, or batteries.

The truth is, more developed markets with more firms in the ‘traditional’ industrial sectors will definitely have to deal with some can of stasis introduced by incumbents lobbying, the inertia from having to restructure the economy, whereas the newer and up-and-coming markets have less to lose, or less industries to cannibalise when they are trying to develop their own industries. China’s advantage of leapfrogging some of the fossil fuels and moving straight from coal to renewables is simply something more fundamental.

The question as a global society is how we can lean on the strengths of different countries to deal with this global climate problem. Geopolitics and global competition can sometimes help. But not when competition turn towards having to re-invent the wheel.

Carbon pricing

I’ve written about carbon credits (here and here); but I never really quite considered them from the perspective of carbon tax, because I generally thought of it as just another instrument that is used to price carbon. In reality, the different mechanisms actually work differently. And even for ‘carbon markets’, where you allow trading (which can take the form of credits or allowances, again slightly different conceptually), the carbon price can take on different meanings depending on the underlying instrument in question.

Singapore’s carbon tax system introduced the idea of allowing carbon credits to ‘offset’ these taxes. And the carbon credits are essentially international carbon credits generated from projects that removes or mitigates emissions in one way or another. This is not new as some other markets have allowed the use of offsets to reduce ETS liabilities (eg. Korea). In Singapore, companies who wish to do so can only have 5% of their carbon tax exposure offset using eligible carbon credits; and there are clear specifications of what works and what doesn’t.

This marriage of carbon taxes and pricing with the generation of quality international carbon credits is something critical to bring the next step of carbon pricing to maturity. Global ‘carbon resources’ in the form of means of removal and sequestration is not uniform, even when we are all sharing the same atmosphere. It is therefore necessary to be able to trade carbon. Technically, because there is negligible transport cost when you ‘trade’ carbon, global pricing of carbon should eventually converge to the same levels. It is potentially as close as it gets to a good that can be pure commodity. Yet because of the whole issue around measurement integrity and the lack of consensus around some of the dodgier types of carbon credit methods, it is going to be very difficult for pricing to converge any time soon. The variations globally in regulating carbon emissions and putting a price on carbon emissions would also serve to slow down global carbon trade.

At the end of the day, there are wider geopolitical and economic considerations blocking stronger climate action. Working along these forces will be necessary since fighting them is rarely an option.

Gas Transition

Natural gas seem to be the fossil fuel which was supposed to be a transition fuel that overstayed its welcome. In fact, it seem to have failed at its job at properly displacing coal and yet today, it is seen as a dirty fuel to be transited away from rather than towards.

That is actually a very anglo-saxon view of the energy transition and if you go around Asia, to some of the fast growing economies you’d realise that notion is somewhat deluded. Natural gas is still growing and providing more energy to more businesses, households and people not because of the gas lobby or some kind of oil & gas conspiracy but that plans laid down in the past to move towards gas are just cranking on and moving forward. Sure, things are not moving as fast as we would like them to, but it is incredibly challenging to keep trying to drive people off gas towards renewable electricity when we have not properly dealt with or created a realistic pathway out of coal power.

A premature transition out of gas, especially for currently non-electrified uses, could be expensive. And electrifying heavy industrial loads when a power system is still dominated by coal, is certainly emissions-blind.

Cutting subsidies

So having ranted incorrectly about energy subsidies, I saw this article about Malaysia and was reminded of this set of principles I suggested to one of the officials at the Single Buyer of Peninsular Malaysia while working with them on a project. These are ideas on how to move towards a regime where subsidies are reduced and does not apply to everyone:

1. Make them transparent: Start by making clear where there is a subsidy; even when there is a blanket subsidy, make sure that the amount of subsidy is clearly shown to those receiving the subsidy, and that the burden of the subsidy is properly attributed, reported, even publicly. Where price controls are used, the implicit subsidy needs to be made explicit.

2. Share a cross-section of the beneficiaries: Often, fuel subsidies are meant to help manage the cost of living for the lower income. But when it is implemented through price controls or blanket subsidies, it disproportionately benefits the largest energy users. By publicising who are the beneficiaries of the subsidy and how much who gets, you can start considering how to reduce the subsidy for select groups of beneficiary that will be impacted the least.

3. Reduce subsidy for beneficiaries not aligned with policy intents: unless the state policy intention is to benefit the fossil fuel industry, there are always some groups benefiting from a blanket subsidy whose profile doesn’t align with the target group you are trying to help.

4. Keep the subsidy only for groups targeted: once the policy intents are clearer and there is social consensus of who the target groups should be, the subsidies can be pared back to be given only to those who need them. This means that subsidies need to shift from producer-side towards consumer-side. This should be aided by improvements in technology, government data-collection, and new channels for disbursing benefits.

The truth is that economics of renewables have improved and could match fossil energy in some cases. Cutting subsidies for fossil fuel will not just help reduce the reliance on them but free up more government resources to accelerate the transition. We should not allow subsidies to stand in the way of the transition.

Energy subsidies

I don’t really remember the last time I dealt with the topic of subsidies. There are huge transfers that takes place in the economy as a result of government interventions through a combination of taxes and subsidies. It is hard to see what the real effects are because the result is always nett of a combination of different forces and programmes. As a result, it is hard to see whether the end result was intentional or not. Often, the end result can be intentional but brought about through a combination of transfers or policies with differing stated intents.

Take for example the whole issue of fuel and energy subsidies. There are explicit and implicit subsidies and they are applied at different levels, to different parts of the value chain, captured by different parties. Of course, the result is to some extent lower cost of energy, but it is also more energy used than otherwise would be. Well, why would you favour wasting energy? Often, it’s because it can help to divert perhaps certain industrial activities that could have downstream impacts such as helping to alleviate poverty, create employment, strengthen social cohesiveness and the list goes on.

After a while, you realised that in the sphere of politics and governance, economics only holds to a certain extent. And competition often can be defined within a single dimension but actually practised over that. What this means is that if you think you’re working hard for school grades, you’d be outcompeted by someone who recognizes that his grades mean little if it is not directed towards getting to a good school or a good job. There is always a greater arena that you are actually competing within.

What this means for renewable energy is that they are not just competing with fossil fuel in terms of adoption and capital for deployment but also consumption and subsidies. Of course there is lots of subsidies going around – for example, for hydrogen. The question is whether it is worthwhile pouring subsidy into that or a more mature energy vector that has the potential to decarbonise (for example, biomethane). However, there are limitations to biomethane or bioenergy because of feedstock limitations, because of the dispersed nature of the feedstock, and the difficulties associated with deployment.

Well, there are also budget limits and land limits. It is strange how people prefer to invest in areas that have more unknowns and uncertainties rather than areas where limits are more ‘known’, but the market could still be sizable. In Australia especially, I think there is incredible upside to taking the long-term view in things because it is a market where sensibilities do tend to eventually prevail.

Originally the intent was to rant about fossil energy subsidies but look where that got me.

Single pivot point

To make a change, we need a single pivot point each time. The pivot point is where things are fixed in place and do not change, and all the other changes hinge on it. And then when we make the next change, we can have another pivot point. But with any one change, we need to select a point of invariance to ensure some kind of order for the change.

In our climate transition today, too many people are trying to change things without a pivot point, thinking that the whole world has to transform. Determining what can be kept constant first is probably a good way to use consensus to drive actions. Then you’ll begin to realise what you are trying to keep the same can have far reaching consequences. For example, if you want to keep energy demand constant and start switching out existing demand into renewables, then you’re making it difficult for economic activities to expand. If you want to keep energy cost constant, then you risk keeping things to status quo and banishing adoption of costlier but greener technologies.

Laying out the trade-offs matter but one can consider how we fix certain parameters and move others first before coming back to revisit these. Take energy costs for example; given the cost of living issues and challenges, governments might want to focus on expanding proven, existing low cost green energy sources and pushing through all manner of regulations, and coordination necessary. Capture of landfill gas to be upgraded into biomethane and upgrading the biogas produced in wastewater treatment plants are low-cost sources of renewable gas that can be plugged into the existing system to displace fossil fuels. Malabar’s biomethane injection plant has just received the Greenpower certification and is the first biomethane plant in Australia to do so, ushering in what we hope to see as an era of using market mechanisms to drive renewable gas and fuel growth as it had done so for renewable electricity in the past decade in Australia.

Some may argue that prolongs the life of fossil infrastructure but we are calling them fossil infrastructure only because they are majority driven by fossil fuels as a result of legacy. One day, those infrastructure could be 100% driving renewable fuels.

Exploring sustainability

I first learnt about Hannah Ritchie‘s book, Not the end of the world, from Bill Gates. Guardian recently published another review of it as the book had just come into the market.

As Bill Gates pointed out, the interesting perspective that Hannah brings is that humans have not quite achieved the notion of ‘sustainability before. The UN notion of sustainability is “meeting the needs of the present without compromising the ability of future generations to meet their own needs”. We were not ‘more sustainable’ in the past as living standards were not great and life was pretty savage; ie. the needs of ‘the present’ wasn’t achieved in the past.

In a sense, it was as though nature had been too harsh to us and we somehow tried to survive that – mostly by ‘conquering’ and ‘reclaiming’ nature. Of course, that somehow begins to push the frontier of the planetary boundaries, and we end up breaching some of them. So the result is that the future needs become somewhat compromised.

Another important aspect of Hannah’s contribution to the book is to encourage people to look into the science and the facts. There had been so much bad press about palm oil and a very sustained assault by Western media on the crop that the productivity of the crop was overlooked. Turning to oilseed alternatives could result in more, rather than less deforestation and hence environmental destruction. Agriculture in the modern times for most part is more about taste and preferences as well as the sway that narratives have – as opposed to optimising agriculture for environment and the world.

Ultimately, we realise from Hannah’s fact-based approach that a lot of the challenges and problems do already have some kind of solution. It is all about adoption, and integrating new narratives in the way we live, and consider what is success for ourselves. Dietary choices are largely a matter of culture and what diet people aspire towards. People’s preferences can be shaped (and hence economics’ attempt at distinguishing exogenous variables from endogenous ones are somewhat moot).

For people to be more aware of the costs, and the challenges of the coordination problem, they must begin from this very fact-based approach that Hannah is leveraging in her optimistic storytelling about the history of human development. We may be struggling towards the solutions that we know (eg. putting a price on carbon and making people pay for it), but at the very least we can agree that this is how we need to move forward with and be aware of the costs and consequences. We need to get people to the bargaining table and work out who has how much to gain or lose. Without creating the transparency and acknowledging the financial, political costs, we end up being caught up in false arguments about technical solutions.

EV charging incentives

For a long time, EV charging infrastructure has been seen as something in the domain of public goods and should be driven by the government. The challenge on the government side is the question of whether it makes sense for them to invest ahead of EV adoption. Investors are nervous about it because EV chargers seem to them like something, which can pop up pretty much anywhere, and there’s no ‘moat’ to support stable revenues even if they serve as an infrastructure practically. Without proper government-regulated structure, it is difficult for investors to put capital into infrastructure in a place where there’s going to be limited utilisation.

Contrast this with petrol kiosk franchises – they are well-established and have demonstrable cash flow, with strong support from the oil & gas companies backing them. Electricity companies are sometimes backing EV charging point networks in order to increase electricity retail but the truth is that electricity distribution works on an entirely different business model from fuel distribution. A lot of investors believe that the petrol kiosks will themselves be the best location for very fast or ultra-fast chargers (usually 10-20 minutes for a full charge). The other fast chargers (1.5-4 hours for a full charge) will likely be in destinations like shopping malls or other commercial buildings.

Yet EV charging infrastructure is so important as a basis to increase EV uptake which the energy transition desperately needs. Electrification of energy needs from transport enables an easier decarbonisation as we can focus on renewable energy in the power sector while transport and other sectors just have to focus on electrification (which of course, can be quite a pain for some sectors – that’s for another day). So how do we increase and improve EV charging infrastructure? Where can we align the incentives? What role should the government play, if at all? And what if it becomes an extremely profitable business down the line?

Pathway to Hydrogen

I keep thinking about the role hydrogen would play in the netzero energy system. It is important because most specialists in the field think it will be incredibly important. But I’m afraid some of them think of the importance not from an energy or thermodynamics perspective but from a technological, socio-economic perspective. I think that is misguided for something that is so nascent and imature.

The solar and battery learning curves cannot be used to project what happens to hydrogen because it is fundamentally a more complex type of project. A lot less plug-and-play compared to solar panels or batteries. For solar panels, the technology takes in light and transform it into power, which in essence is the flow of electrons. There is of course the issue of DC power versus AC power but the inverters will deal with that translation; and you can plug directly to existing electricity grids. Of course, when you have a lot of them the grid must start shifting but at least you get a shot at getting started. And after that you’ve got batteries coming in, again almost ready to work with the existing electrical infrastructure.

Green hydrogen production integrates with the electricity system fine as well; it takes in power, feeds the electrolyser which separates pure water into oxygen and hydrogen, storing away the gas as it is being produced. However, the most valuable output in the process, the hydrogen, needs to be properly stored and transported to where it is needed. And all of these infrastructure do not yet exists! The largest part of the revenue generation problem has not been sorted!

This is why it is so difficult to get hydrogen started, and so expensive to do so even when the technology seem more and more established. The challenge is that a lot of that infrastructure would also serve some of the current fossil gas interests. There are issues of couse with the risks of interest conflicts when the fossil industry push for hydrogen.

The fact that hydrogen is not so plug-and-play to our current system means more evolution is needed before we are ready. Instead of putting direct incentives into hydrogen production, we should be using our resources to solve the problems along the journey to the hydrogen future. A lot of these problems involves collective action, coordination of choices and displacement of swarthe of economic activities that requires proper thought about restructuring.

There is really much more work to do than administering incentives. And this is definitely not an area the government can easily rely on market incentives to accomplish.
